Parity error indicates bad memory. Parity checks compare the memory read with what was writen.
RAM problem.
A parity error always causes the system to hault. On the screen, you see the error message parity error 1 (parity error on the motherboard) or parity error 2 (parity error on an expansion card)
parity error
Parity errors occur when the parity bit, which is used for error detection in data transmission, does not match the expected value. Parity bits can be either even or odd, depending on the system's configuration, and are added to data to ensure that the total number of set bits (1s) is either even or odd. If a parity error is detected, it typically indicates that one or more bits have been altered during transmission, prompting the need for error correction or retransmission of the data.
A parity error always causes the system to halt.

an NMI error
The main causes of parity error are magnetic or electrostatic conditions. This will result mainly into corruption of the computer memory chips.

Data Link layer does the parity error checking Thanks, Samaresh
That's called a "parity violation", which indicates a bit error in the byte. That's the whole purpose of parity ... detecting bit errors, although in order to do it, you have to significantly increase the data load by adding an extra bit to every 7 or 8 bits in the end-user's business traffic.
